The Nutrition Buddy reference
Your portion, worked out
Convert calories or any nutrient per 100g into your serving with this free calculator. Enter the label value and your portion weight in grams.
How it works
Value per 100g × serving weight in grams ÷ 100. Enter calories for a calorie result, or grams of a nutrient for that nutrient’s result. The output uses the same unit as the label value.
For example, 160 kcal per 100g becomes 240 kcal for a 150g serving. This tool does not convert raw weights to cooked weights or millilitres to grams.
